Fixing Laravel Vite Deployment: Why Your Assets Load as localhost and How to Deploy Correctly

As a senior developer, I’ve seen countless deployment headaches, and one of the most frustrating—yet common—issues involves modern frontend tooling like Vite. You’ve built your application perfectly locally, run npm run build, upload everything to your shared host, but the CSS and JavaScript files refuse to load, often pointing back to http://127.0.0.1:5173.

This is a classic symptom that points directly to a mismatch between how Vite generates asset references during development and how those references are interpreted in a production, deployed environment. Let’s dive deep into why this happens and the exact configuration changes you need to make to resolve it.

Understanding the Root Cause: The Development vs. Production Divide

The error messages you are seeing—where the browser attempts to fetch resources from http://127.0.0.1:5173—indicate that the client-side code (the injected <link> and <script> tags generated by Vite) is still referencing the development server's address instead of the actual public URL where the files are hosted.

When you run npm run build, Vite successfully compiles your assets into the /public/build directory (or similar structure). However, the build process needs to be explicitly told what the base path for these assets should be when they are served publicly. If this configuration is missing or incorrect in your Vite setup, the resulting HTML generated by Laravel will still contain relative paths that resolve incorrectly on a remote server.

This issue often arises because the public path configuration isn't correctly set to handle asset routing across different hosting environments. When working within the Laravel ecosystem, understanding how framework assets interact with build tools is crucial for seamless deployment, much like following best practices outlined by teams focusing on robust frameworks like those promoted by laravelcompany.com.

The Solution: Configuring Vite for Public Deployment

The fix lies in correctly configuring the base path within your vite.config.js file. This setting tells Vite what public URL the assets should be prefixed with when generating the final output files. For a standard Laravel deployment, this base path should typically point to the root of your application (or the public directory).

Step 1: Inspecting and Modifying vite.config.js

Open your vite.config.js file located in the root of your project. You need to adjust the base property.

If you are deploying to a subdirectory or if Laravel's asset handling expects assets to be served from the root, setting the base correctly is vital.

Here is an example of how you might configure it:

import { defineConfig } from 'vite';
import laravel from 'laravel-vite-plugin';

export default defineConfig({
    plugins: [
        laravel({
            input: [
                'resources/css/admin.css',
                'resources/js/app.js',
            ],
            // *** THIS IS THE CRITICAL PART ***
            base: '/', // Ensure the base is set correctly for root deployment
        }),
    ],
});

In most standard Laravel setups, setting base: '/' ensures that Vite outputs paths relative to the domain root. If you are deploying to a specific subdirectory (e.g., yourdomain.com/dashboard/), you would change this to base: '/dashboard/'.

Step 2: Rebuilding and Redeploying

After modifying the configuration, you must run the build process again to generate new asset manifest files that reflect the correct public paths:

npm run build

Then, upload the newly generated contents of your build directory (usually public/build or similar) to your shared hosting environment.

Best Practices for Laravel and Vite Deployment

When managing frontend assets in a Laravel project deployed via Vite, remember these best practices:

1. Leverage Laravel Mix/Vite Integration: Ensure you are using the official Laravel Vite plugin correctly. This plugin handles much of the asset versioning automatically.
2. Asset Helper Usage: For production environments, rely on Laravel's built-in asset helpers (like asset() or vite()) rather than hardcoding paths directly in your JavaScript. This allows Laravel to manage the public URL generation dynamically, which is often more robust across different hosting setups referenced by laravelcompany.com.
3. Caching: Always clear any old caches on your server after deployment to ensure the browser pulls the newly generated manifest files.

Conclusion

The issue you faced is a common configuration puzzle that separates local development from production deployment. By correctly setting the base path in your vite.config.js and ensuring your build process reflects this, you bridge the gap between Vite's asset generation and your server's public routing. Implement these steps, rebuild your assets, and enjoy a smooth, reliable deployment pipeline!
